The downward tendency which sets in with any relaxation of the differentiating forces of life is evinced, not only in the extreme case of dissolution in death, but in the well-known relapse of organs which have been artificially developed into exceptional perfection back into their earlier state, when relieved of the strain and left to themselves. Under the tension of a directing mental interest, whether supplied by the animal's own instincts or by the controlling care of man, the organism yields itself to be moulded into more special and highly finished forms; and a series of ascending variations withdraws the nature from its original or first-known type. But wherever we can lift the tension off, the too skilful balance proves unstable, and the law of reversion reinstates the simpler conditions. Only on the higher levels of life do we find a self-working principle of progression: and, till we reach them, development wants its dynamics; and, though there may be evolution, it cannot be self-evolution. These considerations appear to me to break the back of this formidable argument in the middle; and to show the impossibility of dispensing with the presence of Mind in any scene of ascending being, where the little is becoming great, and the dead alive, and the shapeless beautiful, and the sentient moral, and the moral spiritual. Is it not in truth a strange choice, to set up "_Evolution_," of all things, as the negation of _Purpose_ pre-disposing what is to come? For what does the word mean, and whence is it borrowed? It means, to unfold from within; and it is taken from the history of the seed or embryo of living natures. And what is the seed but a casket of pre-arranged futurities, with its whole contents _prospective_, settled to be what they are by reference to ends still in the distance. If a grain of wheat be folded in a mummy-cloth and put into a catacomb, its germ for growing and its albumen for feeding sleep side by side, and never find each other out. But no sooner does it drop, thousands of years after, on the warm and moistened field, than their mutual play begins, and the plumule rises and lives upon its store till it is able to win its own maintenance from the ground. Not only are its two parts therefore relative to each other, but both are relative to conditions lying in another department of the world,--the clouds, the atmosphere, the soil; in the absence of which they remain barren and functionless:--and _this_, from a Cause that has no sense of relation! The human ear, moulded in the silent matrix of nature, is formed with a nerve susceptible to one influence alone, and that an absent one, the undulations of a medium into which it is not yet born; and, in anticipation of the whole musical scale with all its harmonies, furnishes itself with a microscopic grand-piano of three thousand stretched strings, each ready to respond to a different and definite number of aerial vibrations:--and _this_, from a Cause that never meant
